Summary:PURPOSE:To simply duplicate program data by successively reading out program data from an external memory in the 1st information processor and duplicating the program data in an external memory of the 2nd information processor through a data line. CONSTITUTION:The 1st information processor 12a is connected to the 2nd information processor 12b through the data line and a data communication box 18. Program data stored in the 1st external memory 14a are transferred to the 2nd processor 12b through the data line and the box 18 in accordance with a communication control program included in a monitor ROM to be the external memory 14a of the 1st processor 12a. The 2nd processor 12b stores the data sent from the 1st processor 12a in an external memory 14b in accordance with a communication program stored in a monitor ROM to be the 2nd external memory 14b. Thus, the program data is simply duplicated.
